Wire Tier Improvement

Are you having problems with your tier missing ties when everything appears to be normal? Are you missing too many ties? Then maybe the new stagger tie offers the solution.

What happens when both twister hook banks are set at 12:00?

With the hooks at 12:00 the twister hooks will rotate and contact the wires simultaneously, and the twisters will stall at the point depicted above. With the twisters stalled, the cut cylinder will continue to extend. When the wires are cut, the wires from the opposite side of the tier may pull out due to wire tension or drag. The wires may get caught, but occasionally one or more will get away causing a missed tie. Changing the timing of the cut cylinder has little or no effect on the end results.

The Stagger Tie

The stagger tie is having the downstream twisters lag the infeed hooks by 90 to 140 degrees. (In-feed hook pointing at 12:00 and the downstream hook pointing at 3:00 to 4:00 or 8:00 to 9:00) Not only is the tier more reliable, but the wear is greatly reduced.

The above picture depicts the twister hook position at the time the wire is cut. The wire on the in-feed hook is trapped in the twister hook pocket and the downstream hook is just entering the capture area. This ensures the in-feed hooks have a good capture of the wires even in a high drag or tension condition. At the time of capture the downstream hooks have not fully captured the wire, but are relatively in the same position they would be had both hooks been at 12:00.

How to set up?

1. Order our new Timing Cam Weldment needed to prevent twister hook unsafe breakage. See note at the end of the article for correct part number.
2. Set the 120 to 160 degree lag between the two twister banks by:
   1. Rotate the twisters so the master link is accessible at the idler gear.
      (H-37021 on your tier drawing)
      
   2. Lock out and tag out the baler.
   3. Remove the master link on the single 60 twister drive chain.
   4. Remove the chain as necessary from twister drive sprockets so the twister banks may be rotated to achieve the 120 to 170 degree lag. This will be about 5 gear teeth.
      
   5. On a RH tier, rotate sprocket "A" five teeth clockwise and on an LH tier rotate the teeth five teeth counter clockwise. Right and left are determined by standing so the bales coming out of the baler are hitting you in the chest.
   6. Reinstall the chain and master link.
   7. Put the baler into the TIE mode and activate Twist Reverse to reset the baler.
   8. Loosen the existing LS-23 cam and slide towards the hooks to get it out of the way. This will require you to rotate the twisters to gain access to the setscrews.
      
   9. Install the new timing cam, and adjust it until the in-feed twister hooks are at 12:00. Tighten the cam. Put the baler in a manual tie cycle. Hold twist reverse, and note where the twisters stop. Readjust the cam as necessary and repeat the process until the in-feed hook is at 12:00.
3. Reset the flow control to cut faster. We recommend the following setting as a starting point. You will find the setting is not as critical as it was originally.
   1. Loosen the setscrew or lock nut
   2. Turn the adjustment screw in until the stop is reached.
   3. Back out the same adjustment screw 1-1/2 to 2 turns.
   4. Tighten the setscrew or locknut.
